REWINDING-MAOHINE.

SPECIFICATION forming part of Letters Patent N0. 755,212, dated March 2 2, 1904.

Application filed Septeinber 15, 1902. Serial No. 123,374. (No model.)

To all whom it may concern:

Be it known that I, EDWARD E. BRADLEY, a citizen'of the United States, and a resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Rewinding-Machine, of which the following is a specification.

My invention consists of a rewinding-machine in which the silk is wound from the skein-reel onto a bobbin and then is rewound from the said bobbin onto another bobbin.

The object of my invention is to provide a machine of the above character in which the necessity is obviated of removing the bobbins which are wound from the skeins from the machine to another machine for the purpose of rewinding or redrawing, thus. saving a considerable amount of floor-space and doing away with extra handling, machinery, appliances, 620.

At the present time it is common to wind the silk from the skeins onto spools and then take them to a separate redraw-frame, the spools being put on spindles and rewound onto others. This rewinding or redrawing of the silk improves the material for the secondary processes of spinning or warping, but has been seldom done heretofore because of the extra expense attached thereto and the amount of floor-space required.

By the use of my rewinding-machine a single series of driving-pulleys are engaged with r the winding-bobbin and also with the rewinding-bobbin.

In my invention the silk is first wound from the skein onto a combined Winding-bobbin and spindle. The combined winding-bobbin and spindle is preferably provided with heads at its opposite ends for the engagement of driving-pulleys for insuring the even driving of the bobbin at both ends thereof. However, the combined winding-bobbin and spindle may in some instances be driven by a pulley engaging a head at one end thereof, thus dispensing with one of the driving-pulleys. The winding-bobbin is partially supported by a bracket, so that the winding of the silk thereon is started slowly, because of the slipping of the bobbin on the pulleys, and finally brought to full speed without undue strain on the silk as it is unwound from the skein, thus obviating the frequent. breaking of the silk, which is common when the winding-bobbin is entirely supported by the driving-pulley. When the bobbin is full, it is placed in another rack and is rewound onto a rewinding doffing-bobbin and spindle. These two operations are going on at the same time in a single machine and do not require any additional floor-space for the machine and only a slight additional expense in the construction of the machine.

In the accompanying drawings, Figure 1 .represents the rewinding-machine in trans verse vertical section with the skein reel, winding-bobbin, delivery-bobbin, rewindingbobbin, and driving-pulley in position upon one side of the machine, the said parts being removed from the other side of the machine to more clearly illustrate supports therefor. Fig. .2 is a front view of a portion of the machine, showing two adjacent sets of bobbins and their operating mechanisms. Fig. 3 is a transverse section taken in the plane of the line A A of Fig. 1; and Fig. 4 is a detail, on an enlarged scale, of part of one of the brackets which forms a partial support for the combined winding-bobbin and spindle.

The upright of the frame is denoted by 1, and it is provided at its top with a longitudinal shelf. 2;

C A pair of longitudinal tubular braces 3 extend along-the middle of the machine, to

which bracesare secured the brackets 4,which support the skein-reels 5 in the usual manner.

These guide-rails are provided with the usual eyes 12 for directing the threads to the rewinding-bobbins as the rail is reciprocated. These rails may be reciprocated by the usual means. (Not shown herein.)

Brackets 13 are rigidly secured to the side tubular braces 6, which brackets serve to engage the ends of the spindles M 15 of the winding and rewinding bobbins l6 and 17, respectively, for holding the bobbins in engagement with the driving-pulleys 9. Each of these brackets is provided with sockets 18 upon opposite sides thereof for receiving the ends of adjacent spindles 1 1 of the windingbobbins and sockets 19 for temporarily supporting the spindles of the winding-bobbins out of engagement with the driving-pulley. This bracket 13 is further provided upon opposite sides thereof with sockets 20 for receiving the ends of adjacent spindles 15 of the rewinding-bobbins 17 and with sockets 21 for temporarily supporting the said rewinding-bobbins out of engagement with the driving-pulleys 9. The ends of the brackets 13 serve to support the longitudinally-reciprocating thread-guide rails 22, which guide the threads from the skein onto the winding-bobbins as the rails 22 are reciprocated. These rails may be reciprocated by the usual means. (Not shown herein.)

Brackets 23 are rigidly secured to the shelf 2 at the top of the machine, each of which brackets is provided with sockets 24 upon 0pposite sides thereof for supporting adjacent ends of the spindles 1 1 of the winding-bobbins 16, which bobbins in this instance are used as delivery-bobbins. The spindle l4 and bobbin 16 are combined and the bobbin provided at its opposite ends with cylindrical heads 25 for engaging the peripheries of the two driving-pulleys 9 of a pair to insure an even winding of the silk on the bobbin.

The dofiing or rewinding bobbin 17 is made separate from its spindle 15, so that when the bobbin is completely wound it may be removed from the spindle for further manipulation. in this case one of the cylindrical heads 25 at the opposite ends of the bobbin is made removable from the spindle in the usual manner.

The weight of each of the combined winding-bobbins and spindles is partially taken by the bracket 13 by providing an incline 26 along the socket 18, upon which the spindle 14 rests. This arrangement insures the gradual starting of the winding-bobbin and prevents the breaking of the silk as it comes from the skein.

In the construction hereinabove described it will be seen that while the silk is being wound upon the winding-bobbins 16 the silk may be at the same time also rewound upon the doifing-bobbins 17 from the winding-bobbins 16, which serve as delivery-bobbins when supported in the brackets 23.

What I claim is- A rewinding-machine comprising a suitable frame, a driving-pulley, means for supporting a skein-reel, brackets for supporting a winding-bobbin used as a delivery-bobbin, the said driving-pulley serving to wholly support and drive a rewinding-bobbin and drive and partially support a winding-bobbin and brackets having vertical slots for retaining the rewinding-bobbin in position on the pulley and having inclines for taking part of the weight of the winding-bobbin off the driving-pulley.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 29th day of August, 1902.

EDWARD E. BRADLEY.
